+# RAPPORT — Architektur-Übersicht
+
+> Studio-Management für Architekturbüros. Tauri 2.x Desktop-App, React 19 Frontend, Rust-Backend (minimal), localStorage-only Persistierung. Solo-Dev: Karim.
+> Dieses Dokument ist die **Karte** der Codebase. Es ersetzt nicht das Lesen einzelner Dateien, soll aber verhindern, dass jede Session bei Null anfangen muss.
+
+---
+
+## 1. Mentales Modell in einem Absatz
+
+RAPPORT ist eine **monolithische SPA**: ein React-Root in [App.jsx](src/App.jsx) hält den **gesamten** App-State in einem `useState({...})`, persistiert ihn synchron in `localStorage` unter dem Key `studio_data_v1`, und übergibt ihn als Props an lazy-geladene Views. Es gibt **kein Routing-Framework** (View-Wechsel via String-State), **kein State-Library** (kein Redux/Context/Zustand), **kein TypeScript**, **kein CSS-Framework** (alles inline `style={{}}` oder ein 700-Zeilen `<style>`-Block in App.jsx). Der **Rust-Teil** ist 109 Zeilen und macht nur drei Dinge: System-Tray, Window-Hide-on-Close, Plugin-Registrierung (Updater, Process, Log). Es gibt **keine `#[tauri::command]`** — Frontend ↔ Backend kommuniziert nur über das Event `rapport:navigate` (Tray → Frontend). Alle Daten sind im WebView-`localStorage`, nichts wird in Rust gespeichert.
+
+**Konsequenz:** Wenn etwas mit Daten passiert, ist es JS. Wenn etwas mit dem Fenster/Tray/Update passiert, ist es Rust. Es gibt keine dritte Stelle.

+
+## 3. Datenfluss — Wie Updates wirklich passieren
+
+```
+User-Interaktion in View
+     │
+     ▼  onChange / onClick
+View ruft eine der zwei Props auf:
+     │
+     ├── update(key, value)      → save({ ...data, [key]: value })  // Top-Level-Field
+     └── saveAll(newData)         → save(newData)                    // Atomar
+                                     │
+                                     ▼
+                              setData(newData)
+                              localStorage.setItem("studio_data_v1", JSON.stringify(newData))
+                                     │
+                                     ▼
+                              React re-rendert die Hierarchie
+```
+
+**Wichtig:**
+- `save()` schreibt **synchron** bei jedem Update — kein Debouncing. Bei großen `data`-Objekten kann das spürbar werden.
+- Es gibt **kein Backup, kein Conflict-Resolution**. Wenn der User zwei App-Fenster hat (passiert kaum, weil Single-Window), überschreibt das letzte gewinnt.
+- Kein Schema-Validator beim Laden — wenn `localStorage` korrupt ist, crasht es im Render.
+
+**`data` Top-Level-Struktur** (definiert in [constants.js](src/constants.js)):
+```
+{
+  settings,           // Studio-Daten: Name, IBAN, MWST, Stundensätze, Rollen, …
+  persons[],          // Kunden + Partner (vereint seit v0.5)
+  projects[],         // Projekte mit SIA-Phasen / Budget / Billing-Type
+  timeEntries[],      // Stundeneinträge
+  invoices[], quotes[],
+  expenses[], internalExpenses[],
+  employees[], absences[], ferienEntries[], lohnEntries[],
+  protocols[], deliveryNotes[], letterTemplates[],
+  dashboardTemplates[], appRoles[], users[]
+}
+```
+
+---
+
+## 4. Navigation & State-Verwaltung
+
+**Navigation** ist eine String-State-Machine in [App.jsx](src/App.jsx):
+- `const [view, setView] = useState("dashboard")`
+- Jede View ist ein String-Identifier (`"dashboard"`, `"projects"`, `"time"`, …)
+- `navigate(newView)` schiebt auf einen Ref-basierten History-Stack (Browser-ähnliches Vor/Zurück)
+- Drill-down via `selectedProjectId` etc. (zweiter State neben `view`)
+
+**Modals:** Inkonsistent — manche Views nutzen `modal: { type, id }`, andere haben mehrere separate `useState` (siehe [Invoices.jsx](src/views/Invoices.jsx): `setModal`, `setNewInvModal`, `setAkontoModal`). Es gibt keinen zentralen Modal-Manager.
+
+**Sessions/Auth:**
+- `sessionStorage.rapport_user` — angemeldeter User (gestrippt von Credentials)
+- Login per PBKDF2-SHA-256 (100k Iter, 16-Byte Salt) — siehe `hashPassword`, `verifyPassword` in [utils.js](src/utils.js)
+- Lockout: 5 Fehlversuche → 60s Sperre ([Login.jsx](src/views/Login.jsx))
+- Auto-Upgrade: legacy plaintext-Passwörter werden beim ersten erfolgreichen Login zu PBKDF2 migriert ([App.jsx:143-161](src/App.jsx#L143-L161))
+
+**Weitere `localStorage`-Keys (alle `rapport_*`-prefixed):**
+| Key | Zweck |
+|---|---|
+| `studio_data_v1` | **Die Hauptdaten** (alles außer Settings unten) |
+| `rapport_dark` | Dark Mode (`"1"`/`"0"`) |
+| `rapport_sidebar_collapsed` | Sidebar collapsed (`"1"`/`"0"`) |
+| `rapport_zoom` | UI-Zoom-Faktor |
+| `rapport_changelog_seen` | Zuletzt gesehene Changelog-Version |
+| `rapport_v0_5_migrated` | Marker für abgeschlossene Migration |
+| `rapport_update_skipped_version` | Vom User übersprungene Update-Version |
+| `rapport_update_last_check` | ISO-Timestamp letzter Update-Check |
+| `sessionStorage.rapport_user` | Aktive Session |
+
+---
+
+## 5. Views — Inventar
+
+Alle Views liegen in [src/views/](src/views/), werden in [App.jsx](src/App.jsx) per `React.lazy()` geladen und über Props `{ data, update, saveAll, modal, setModal, currentUser, … }` versorgt.
+
+| View | Zeilen | Zweck | Komplexität |
+|---|---:|---|---|
+| [Projects.jsx](src/views/Projects.jsx) | 1781 | List + Detail, SIA-Phasen, Quoten-Zuordnung, Nachträge | **Sehr hoch** |
+| [Time.jsx](src/views/Time.jsx) | 1538 | Wochen-Grid mit Drag&Drop, Tag/Woche/Monat, Absenzen | **Sehr hoch** |
+| [Invoices.jsx](src/views/Invoices.jsx) | 1467 | Rechnungen, Akonto, QR-Bill, Mahnungen, Planer | **Sehr hoch** |
+| [Employees.jsx](src/views/Employees.jsx) | 1298 | Multi-Tab: Stammdaten, Absenzen, Ferien, Lohnabschluss | **Sehr hoch** |
+| [Quotes.jsx](src/views/Quotes.jsx) | 980 | Offerten: SIA / manuell / frei, Übernahme als Projekt | Hoch |
+| [Protocols.jsx](src/views/Protocols.jsx) | 978 | Sitzungsprotokolle (Beschluss/Info/Aufgabe), Mahnung-Modul | Hoch |
+| [Expenses.jsx](src/views/Expenses.jsx) | 914 | Mitarbeiter-Spesen + interne Ausgaben, Bild-Upload | Hoch |
+| [Settings.jsx](src/views/Settings.jsx) | 869 | 7 Tabs: Studio, Dokumente, Team, Kalender, System, Support, Profil | **Sehr hoch** |
+| [StudioBudget.jsx](src/views/StudioBudget.jsx) | 847 | Revenue-Sparklines, Aggregation Rechnungen/Quoten | Hoch |
+| [Dashboard.jsx](src/views/Dashboard.jsx) | 762 | Drag&Drop Widget-Layout, Template-System | Hoch |
+| [Persons.jsx](src/views/Persons.jsx) | 682 | Kunden + Partner (seit v0.5 vereint) | Mittel |
+| [Setup.jsx](src/views/Setup.jsx) | 423 | 7-Step-Wizard für Neuinstallation | Mittel |
+| [Pinboard.jsx](src/views/Pinboard.jsx) | 417 | Blog-artige Notizen, kategorisiert | Mittel |
+| [Accounting.jsx](src/views/Accounting.jsx) | 374 | CSV-Export, Jahreszahlen, MwSt-Berechnung | Mittel |
+| [Payroll.jsx](src/views/Payroll.jsx) | 344 | Monats-Lohnzettel, BVG-Sätze, Abzüge | Mittel |
+| [DeliveryNotes.jsx](src/views/DeliveryNotes.jsx) | 294 | Lieferscheine | Niedrig |
+| [Login.jsx](src/views/Login.jsx) | 197 | Login + Brute-Force-Lockout | Niedrig |
+| [Documents.jsx](src/views/Documents.jsx) | 194 | Router zu Protokolle/Lieferscheine/Briefe | Niedrig |
+| [MigrationScreen.jsx](src/views/MigrationScreen.jsx) | 141 | v0.5-Migration-Wizard (wenn alte Daten erkannt) | Niedrig |
+| [Letters.jsx](src/views/Letters.jsx) | 114 | Brieftemplates mit Placeholdern (`{{client}}`, …) | Niedrig |
+
+---
+
+## 6. utils.js — Business-Logik-Bibliothek
+
+[utils.js](src/utils.js) ist isoliert und gut testbar. Die wichtigsten Gruppen:
+
+**Kalkulation:**
+- `calcSIAHours(baukosten, schwierigkeit, phasen)` — SIA-102-Formel `p = Z1 + Z2/∛B`
+- `calcManualHours(phases, roles)` — Stundenansatz × Stunden pro Rolle
+- `deriveQuoteBudget(linkedQuotes, allQuotes, roles)` — Aggregiert Offerten zu Projekt-Budget
+- `calcLohn(emp, monat, spesen, bonus)` — AHV/ALV/BVG/NBU/KTG/Quellensteuer
+
+**Crypto / Auth:**
+- `hashPassword(password, saltHex)` — PBKDF2-SHA-256, 100k Iter, via Web Crypto
+- `verifyPassword(password, user)` — Constant-Time
+- `withHashedPassword(user, password)` — Upgrade legacy → hashed
+- `stripCredentials(user)` — Entfernt `password`, `passwordHash`, `passwordSalt`
+
+**Sicherheit:**
+- `sanitizeHtml(html)` — Allowlist (`<p>`, `<br>`, `<b>`, `<a>`, …), blockiert `<script>`, `javascript:`, `on*`-Handler
+
+**Formatierung (de-CH):**
+- `formatCHF(amount)` → `"CHF 1'234.50"`
+- `formatDate(iso)` → `"14. Mai 2025"`
+- `roundCHF(amount)` → 5-Rappen-Rundung
+- `formatHours(minutes)` → `"2h 30m"`
+
+**Schweizer QR-Rechnung:**
+- `isQRIban(iban)` — IID-Range 30000–31999
+- `formatIban(iban)` → 4er-Blöcke
+- `generateQRReference(invoiceNumber)` → 27-stellige Referenz mit Mod10-Prüfziffer
+- `mod10(input)` — Schweizer Modulo-10-Algorithmus
+
+**Templates / Nummerngenerierung:**
+- `applyProjectNumberFormat`, `applyProtoNumberFormat` — Template-Syntax wie `{YYYY}/{NN}`
+- `parseSeqFromNumber`, `nextProtoSeq`
+- `buildReminderLetter(inv, nr, …)` — Mahnungstexte (1./2./3. Mahnung)
+- `buildPdfName(format, content, settings)` — Sanitierter Dateiname
+
+**Sonstiges:**
+- `exportBuchhaltungCSV(data, year)` — Voller Jahresexport
+- `migrateDashboardLayout(val)` — Alte Widget-IDs → Row-basiertes Layout
+- `getFeiertageForYear`, `getWorkdaysInMonth`, `getSollStunden`
+
+---
+
+## 7. Print-Modul
+
+[src/print/PrintComponents.jsx](src/print/PrintComponents.jsx) (~1200 Zeilen) exportiert `<PrintView>`, das via `setPrintContent(...)` aus App.jsx getriggert wird.
+
+**Content-Typen:** `invoice`, `invoice+qr`, `qrbill`, `quote`, `letter`, `lieferschein`, `protokoll`, `lohn`, `studioBudget`, `buchhaltung`, `projectDetail`, `projectsOverview`, `mitarbeiterOverview`, `timeReport`.
+
+**Druck-Trigger:** `getCurrentWebviewWindow().print()` (Tauri WebView) oder Fallback `window.print()` (Browser).
+
+**Schweizer QR-Rechnung:** Lib `swissqrbill` (lokal installiert), erzeugt SVG für 100% akkuraten Druck. Format: 105mm × 210mm, separate `@page`-Regel.
+
+**Styles:** Inline + `@page`, `print-color-adjust: exact`. Margins konfigurierbar über `settings.pageMargin{Top,Bottom,Left,Right}`.
+
+---
+
+## 8. Rust-Backend ([src-tauri/src/lib.rs](src-tauri/src/lib.rs))
+
+**Alles in 103 Zeilen.** Keine `#[tauri::command]`. Kein Filesystem, kein HTTP, keine DB.
+
+**Was er macht:**
+1. **System-Tray** mit 5 Nav-Items (`nav:dashboard`, `nav:time`, `nav:projects`, `nav:buchhaltung`, `nav:settings`) + `show` + `quit` ([lib.rs:47-60](src-tauri/src/lib.rs#L47-L60))
+2. **Tray-Click** → Fenster anzeigen + fokussieren ([lib.rs:81-90](src-tauri/src/lib.rs#L81-L90))
+3. **Tray-Nav-Click** → `emit("rapport:navigate", "<view>")` ans Frontend ([lib.rs:77](src-tauri/src/lib.rs#L77))
+4. **Window-Close (X)** → Hide statt Quit, gesteuert durch `Arc<AtomicBool> is_quitting` ([lib.rs:25-35](src-tauri/src/lib.rs#L25-L35))
+5. **Plugins registrieren:** `updater`, `process` (für Relaunch nach Update), `log` (nur Debug)
+
+**Frontend lauscht** in [App.jsx:191](src/App.jsx#L191):
+```js
+listen("rapport:navigate", (event) => setView(event.payload))
+```
+
+**Capabilities** ([src-tauri/capabilities/default.json](src-tauri/capabilities/default.json)) — bewusst minimal:
+- `core:default`
+- `core:webview:allow-print` (für `window.print()`)
+- `updater:default`
+- `process:allow-restart` (für Relaunch nach Update)
+- **Nichts** für `fs:*`, `shell:*`, `http:*`, `dialog:*`, `clipboard:*`
+
+**Tauri-Plugins (Cargo.toml):**
+- `tauri-plugin-updater` v2
+- `tauri-plugin-process` v2
+- `tauri-plugin-log` v2
+- `serde` 1.0, `serde_json` 1.0
+
+**Bekannte Fragilitäten:**
+- `app.default_window_icon().unwrap()` — panicked, wenn Icon fehlt ([lib.rs:64](src-tauri/src/lib.rs#L64))
+- Hardcoded `"main"`-Label für Window, Hardcoded `"nav:"`-Prefix — wenn Frontend Konventionen ändert, bricht Tray
+- Keine Tests in Rust
+
+---
+
+## 9. Updater-Pipeline End-to-End
+
+```
+release.sh (lokal, manuell aufgerufen)
+  ├─ liest VERSION aus tauri.conf.json + package.json (Mismatch → Exit)
+  ├─ ⚠️ Cargo.toml wird NICHT geprüft
+  ├─ Lädt Private Key aus ~/.tauri/rapport_updater.key (kein Passwort)
+  ├─ npx tauri build   (mit TAURI_SIGNING_PRIVATE_KEY env)
+  ├─ findet .app.tar.gz + .sig in src-tauri/target/release/bundle/macos/
+  └─ schreibt latest.json (Repo-Root) mit version, signature, url, pub_date
+     └─ url zeigt auf Gitea Release Asset (manuell hochzuladen)
+
+User (manuell):
+  ├─ Gitea-Webinterface: Release mit Tag <VERSION> (ohne v-Prefix) erstellen
+  ├─ .app.tar.gz (+ optional .dmg) hochladen
+  └─ git add latest.json && git commit && git push origin main
+
+App-Start (in jeder installierten Version):
+  ├─ UpdateNotifier.jsx: setTimeout 1.5s → checkForAppUpdate({ silent: true })
+  ├─ Tauri-Plugin GET https://git.kgva.ch/karim/RAPPORT/raw/branch/main/latest.json
+  ├─ Verifiziert Signature gegen pubkey aus tauri.conf.json (Minisign)
+  ├─ Vergleicht latest.json.version mit getVersion()
+  └─ Wenn neuer → Modal mit "Installieren / Später / Diese Version überspringen"
+
+Installation:
+  ├─ update.downloadAndInstall(onProgress)  // lädt von url in latest.json
+  └─ relaunch() (via plugin-process)
+```
+
+**Updater-Komponenten im Frontend:**
+- [src/utils/updater.js](src/utils/updater.js) (49 Z.) — Wrapper, kapselt Skip-Logik in `localStorage`
+- [src/components/UpdateNotifier.jsx](src/components/UpdateNotifier.jsx) (163 Z.) — Auto-Check beim Start, Modal mit Progress-Bar
+- [src/components/UpdatesSupport.jsx](src/components/UpdatesSupport.jsx) (197 Z.) — Settings-Tab "Updates & Support", manueller Check, ignoriert Skip
+- Custom DOM-Event: `window.dispatchEvent(new CustomEvent("rapport:check-update"))` — UpdatesSupport triggert manuell
+
+**Aktueller `latest.json`:** nur `darwin-aarch64` (Apple Silicon). **Kein Intel-Build, kein Windows-Build, kein Linux-Build.** Wer auf x86_64-Mac oder anderem OS installiert, bekommt keine Updates.
+
+**Signatur-Setup (Minisign):**
+- Private Key: `~/.tauri/rapport_updater.key` (User-Home, **niemals** im Repo, gitignored via `*.key`)
+- Public Key: base64 in `tauri.conf.json` → `plugins.updater.pubkey`
+- Kein Passwort (`TAURI_SIGNING_PRIVATE_KEY_PASSWORD=""`)
+
+---
+
+## 10. Build & Release-Workflow
+
+**Versions-Bump betrifft drei Dateien — alle drei müssen synchron sein:**
+1. [package.json](package.json) → `"version"`
+2. [src-tauri/tauri.conf.json](src-tauri/tauri.conf.json) → `"version"`
+3. [src-tauri/Cargo.toml](src-tauri/Cargo.toml) → `[package] version`
+
+**Zusätzlich für jeden Release:**
+4. [src/App.jsx](src/App.jsx) → Changelog-Entry in `CHANGELOGS`-Array (hardcoded in JSX)
+5. [src/App.jsx](src/App.jsx) → `rapport_changelog_seen`-Vergleichswert (im Changelog-Modal-Close-Handler)
+
+> ⚠️ `release.sh` prüft nur 1+2. **Cargo.toml-Mismatch bleibt unbemerkt.**
+
+**Dev-Workflow:**
+```bash
+npm run dev          # Vite-Server auf http://localhost:3000
+npx tauri dev        # Native Window + HMR
+npm run lint         # ESLint (manuell — kein Pre-Commit-Hook)
+```
+
+**Release-Workflow:**
+```bash
+# 1. Versionen in package.json, tauri.conf.json, Cargo.toml + Changelog-Entry hochziehen
+# 2. Commit
+# 3. Release-Script:
+./scripts/release.sh
+# 4. In Gitea-UI: Release <VERSION> erstellen (Tag OHNE v-Prefix — latest.json-URL nutzt /<VERSION>/), .app.tar.gz hochladen
+# 5. git add latest.json && git commit -m "Release X.Y.Z" && git push origin main
+# 6. git tag -a <VERSION> -m "..." && git push origin <VERSION>
+```
+
+> Die [README.md](README.md)-Release-Sektion erwähnt `scripts/release.sh` nicht und ist veraltet.
+
+---
+
+## 11. Konventionen
+
+**Sprache:**
+- **UI-Strings: Deutsch** ("Zeiterfassung", "Buchhaltung", "Beenden")
+- **Code-Identifier: Englisch** (`isQuitting`, `setView`, `currentUser`)
+- **Wenig Inline-Kommentare** — wenn vorhanden, meist Deutsch
+
+**Naming:**
+- Komponenten/Views: PascalCase, eine Datei = ein Default-Export (ggf. mit Named-Exports für Sub-Views)
+- Utils: camelCase
+- Dateien: PascalCase für Components/Views, lowercase für constants/utils
+
+**Styling:**
+- Inline-Styles dominieren (über 200 in [Invoices.jsx](src/views/Invoices.jsx) allein)
+- Globale Klassen: `.btn`, `.card`, `.pill`, `.filter-bar`, `.modal` — definiert im `<style>`-Block in [App.jsx](src/App.jsx)
+- CSS-Variablen für Theming: `--bg`, `--text`, `--border`, … (Dark Mode via `data-theme`-Attribut)
+- **Kein** Tailwind, **kein** CSS-Module, **kein** styled-components
+
+**ESLint** ([eslint.config.js](eslint.config.js)): Flat-Config mit `js.configs.recommended`, `reactHooks.configs.flat.recommended`, `reactRefresh.configs.vite`. Kein Prettier, kein Husky, kein lint-staged.
+
+**Imports:** Stdlib oben (React), dann Constants/Utils, dann lokale Components. Keine Pfad-Aliase (`~/`, `@/` werden **nicht** verwendet — relative Pfade `../foo`).
+
+---
+
+## 12. Wo es weh tut — Realistische Schwachstellen
+
+1. **Vier "God Components"** über 1200 Zeilen ([Projects](src/views/Projects.jsx), [Time](src/views/Time.jsx), [Invoices](src/views/Invoices.jsx), [Employees](src/views/Employees.jsx)) — Refactoring riskant ohne Tests, Sub-Komponenten sind intern definiert statt extrahiert.
+2. **App.jsx ist 823 Zeilen** und macht: Auth, State, Migration, Sidebar, Modals, Changelog, About, Print-Routing, Hotkeys, Navigation-History, Theme. Jede Änderung an App.jsx ist hochriskant — sie betrifft alles.
+3. **Inline-Styles ohne Konvention** — Spacing/Farben sind über das Projekt verstreut, kein Design-Token-System.
+4. **Modal-State chaotisch** — manche Views haben `{type,id}`, andere mehrere `useState`. Kein zentraler Manager.
+5. **Keine Tests.** Nichts. Kein Vitest, kein Cypress, kein Rust-Test. Kalkulationen in `utils.js` wären leicht testbar.
+6. **Kein TypeScript.** Bei 18k Zeilen JSX ohne Types ist jedes Schema-Refactor Risiko.
+7. **Kein Error-Boundary** — wenn eine lazy-geladene View crasht, weißer Screen.
+8. **`localStorage` ohne Schema-Validierung** — korrupte Daten crashen im Render.
+9. **Keine CI**, keine Pre-Commit-Hooks. Linting muss man sich selbst merken.
+10. **Updater nur für Apple Silicon** — wenn User x86_64-Mac/Windows/Linux hat, kein Update.
+11. **README-Release-Sektion veraltet** — erwähnt `scripts/release.sh` nicht.
+12. **`release.sh` prüft Cargo.toml-Version nicht** — Inkonsistenz bleibt unbemerkt.
+13. **`.unwrap()` im Tray-Icon-Load** in [lib.rs:64](src-tauri/src/lib.rs#L64) — Startup-Panic möglich, wenn Icon fehlt.
+
+---
+
+## 13. Wenn-du-anfasst-Hinweise
+
+| Bereich | Risiko | Notiz |
+|---|---|---|

+## 14. Offene Fragen / Nicht-Validiertes
+
+- Wo werden Bild-Uploads (Receipts in Expenses, Logo in Settings) gespeichert? Vermutlich Base64 in `data` → wächst `localStorage` unkontrolliert.
+- Wie groß darf `data` werden, bevor `localStorage` (5–10 MB Limit) bricht? Aktuell ohne Monitoring.
+- PDF-Export: aktuell nur `window.print()` → User-PDF-Dialog. Kein direkter File-Save.
+- Multi-User-Workflow: `users[]` in `data`, aber nur ein Browser-localStorage → keine echte Mehrfachnutzung.

+# Anweisungen für Claude
+
+Dieses Dokument wird in **jede** Claude-Session automatisch geladen. Es ist die kürzeste Form: Was du wissen musst und was du tun/lassen sollst. Details stehen in [ARCHITECTURE.md](ARCHITECTURE.md) — **lies sie, bevor du nicht-triviale Änderungen machst.**
+
+---
+
+## Was das Projekt ist
+
+**RAPPORT** — Tauri 2.x Desktop-App für Architekturbüros. React 19 (kein TypeScript), minimaler Rust-Backend (System-Tray + Updater, keine Tauri-Commands). Solo-Dev: Karim. Daten leben in `localStorage` unter Key `studio_data_v1`. macOS Apple Silicon ist die primäre Plattform.
+
+Architektur in einem Satz: **App.jsx hält den gesamten State, übergibt ihn an lazy-geladene Views als Props, persistiert synchron in localStorage. Rust macht nur Tray + Update.**
+
+→ Vollständige Karte: [ARCHITECTURE.md](ARCHITECTURE.md)
+
+---
+
+## Befehle
+
+```bash
+npm run dev          # Vite-Server auf http://localhost:3000
+npx tauri dev        # Native App-Window mit HMR (für UI-Verifikation)
+npm run lint         # ESLint
+npm run build        # Frontend-Build (dist/)
+npx tauri build      # Vollständiges App-Bundle
+./scripts/release.sh # Release-Build mit Signatur — NUR auf explizite Anweisung
+```
+
+Es gibt **keine Tests**, keine CI, keinen Pre-Commit-Hook. Korrektheit ist Augenmaß.
+
+---
+
+## Sprache
+
+- **Antworte auf Deutsch.** Karim arbeitet auf Deutsch.
+- **UI-Strings im Code: Deutsch** ("Zeiterfassung", "Buchhaltung", "Beenden").
+- **Code-Identifier: Englisch** (`setView`, `currentUser`, `isQuitting`).
+
+---
+
+## Vor jeder Änderung — die drei Reflexe
+
+1. **Wenn es um Daten/State geht** → schau in [App.jsx](src/App.jsx) (Top-Level-State, Migrations, `save()`, `update()`). Kein Zustand existiert ausserhalb davon.
+2. **Wenn es um Logik geht** (Kalkulation, Format, Hash, QR-Bill) → schau in [utils.js](src/utils.js). Dort sind isolierte Funktionen — wahrscheinlich gibt es schon eine.
+3. **Wenn es um das Datenmodell geht** → schau in [constants.js](src/constants.js) (`defaultData` ist die Shape-Referenz).
+
+---
+
+## Tu — Konventionen die hier gelten
+
+- **Inline-Styles** (`style={{}}`) sind etabliert. Keine Tailwind-Vorschläge, keine CSS-Module einführen, ohne dass Karim das initiiert.
+- **Globale Klassen** (`.btn`, `.card`, `.pill`, `.modal`, `.filter-bar`) sind in [App.jsx](src/App.jsx)'s `<style>`-Block definiert — nutze sie statt eigene zu erfinden.
+- **CSS-Variablen** für Theming (`--bg`, `--text`, `--border`, …). Dark Mode ist `data-theme="dark"` am Root. Niemals harte Farben einbauen, ohne CSS-Variable zu prüfen.
+- **Lazy-Loaded Views** — neue Top-Level-Screens in [App.jsx](src/App.jsx) mit `React.lazy()` einbinden, nicht direkt importieren.
+- **Props-Pattern:** Views bekommen `{ data, update, saveAll, modal, setModal, currentUser, … }`. Kein Context, kein Redux. Wenn du State teilst, mach es über `data` oder hebe ihn in App.jsx.
+- **`update(key, value)`** für Top-Level-Field-Updates, **`saveAll(newData)`** für atomare Multi-Field-Updates.
+- **Relative Imports** (`../utils.js`), keine Pfad-Aliase.
+- **Deutsch in UI-Strings**, auch in neuen Features.
+
+---
+
+## Lass — Stolperfallen
+
+- **Kein TypeScript einführen** ohne expliziten Auftrag — die Migration wäre eigenständig zu diskutieren.
+- **Keine Test-Suite "nebenbei" aufsetzen** — sinnvoll, aber separate Entscheidung.
+- **Keine Context-/Redux-/Zustand-Provider hinzufügen** — das Single-Root-State-Pattern ist bewusst.
+- **Keine Tauri-Commands (`#[tauri::command]`) erfinden**, ohne mit Karim zu klären. Die Architektur ist absichtlich Frontend-zentriert.
+- **Keine neuen `localStorage`-Keys** erfinden, ohne `rapport_`-Prefix und Eintragung in [ARCHITECTURE.md §4](ARCHITECTURE.md).
+- **Niemals Tests/Lint mit `--no-verify` umgehen** — wenn ein Pre-Commit-Hook fehlt, fehlt er aus Absicht; wenn einer da ist, ist das Karims Entscheidung.
+- **`localStorage` ist die Wahrheit** — keine Versuche, parallele Persistierung (IndexedDB, Tauri AppData) hinzuzufügen.
+
+---
+
+## Releases — heißes Eisen
+
+**Mach niemals einen Release auf eigene Faust.** Auch nicht "halb" (kein Versions-Bump, kein `release.sh`, kein Tag, kein `latest.json`-Edit), es sei denn Karim sagt es explizit.
+
+Wenn ein Release gewünscht ist, denke an:
+- Version in **drei** Dateien synchron: [package.json](package.json), [src-tauri/tauri.conf.json](src-tauri/tauri.conf.json), [src-tauri/Cargo.toml](src-tauri/Cargo.toml). `release.sh` prüft Cargo.toml **nicht** — du musst manuell.
+- Changelog-Entry in [App.jsx](src/App.jsx)'s `CHANGELOGS`-Array + den `rapport_changelog_seen`-Vergleichswert.
+- `release.sh` braucht `~/.tauri/rapport_updater.key` — wenn fehlt, abbrechen, nicht generieren.
+- Asset-Upload auf Gitea und `latest.json`-Commit sind **manuelle** Schritte.
+
+Details: [ARCHITECTURE.md §9 + §10](ARCHITECTURE.md).
+
+---
+
+## UI-Verifikation
+
+Wenn du Frontend-Änderungen machst, die optisch wirken, **starte `npx tauri dev`** und schau, ob es funktioniert. ESLint und Type-Checking gibt es hier nicht — also ist Augenschein die Verifikation. Wenn du es nicht selbst öffnen kannst, sag das explizit, anstatt "fertig" zu melden.
+
+---
+
+## Wenn du etwas Neues findest
+
+Wenn du beim Arbeiten merkst, dass [ARCHITECTURE.md](ARCHITECTURE.md) falsch oder veraltet ist (z.B. neue Views, neue Konventionen, Refactor): **update sie im selben Commit**. Sie ist die Karte — wenn sie verrottet, war die Mühe umsonst.
+
+Wenn du eine wiederkehrende Anweisung von Karim bekommst, die hier fehlt: schlag vor, sie in CLAUDE.md zu ergänzen.
